To all whomii mag/concern:

Be it known that 1, CHARLES "T. OSBORNE, a citizen ot the tlniteii States of America, residing at thecit "of St. Louis, Static of Missouri, United? tates of America, have invented a certain new and useful Explosion-Turbine, ofwliich'the followingis such a full, clear, and eXa'ctld-escription as will enable. any one skilled in the art to which it appertains to make and use: the same, reference being had'to'the accompanying drawin s, forming part of't'his specification.

1y ihventl'on relates to a turbine rnotor operated by explosivei fluid, and its objects are't'o proth'ice a motor of this type, whichis light and eiiicient and which has no reciproeating. parts.

In the preferred form oi myinvention I employ a revolving member havihg. combustion chambers communicating "with the supply of tuel throughmpening in a throttle plate or disk against 'w'hibh the revolving member bears and which serves as a closure for the single opening of each combustion chamber. The gas produced by the explosion of fuel in the combustion chambers is discharged into a turbine of ordinary construction, provided with the usual movable and stationary vanes. The revolving portion of the turbine is keyed to the same shaft as the revolving member carrying the combustion chambers.

In the accompanying drawings, which illustrate one embodiment of my invention, Figure 1 is a longitudinal section; Fig 2 is a top elevation; Fig. 3 is an end elevation; and Fig. 4: is a cross sectional view taken on the line a a of Fig. 1.

1 represents the casing of the turbine, which is provided With the usual stationary vanes 2. The rotor of the turbine is provided with the usual vanes or buckets 3, and is connected to a shaft 1. One end of the turbine case is closed by a stationary member 5. In the form shown this member 5 is provided with two fuel reservoirs 6, supplied from a fuel pump 7, and with two vacuum chambers 8 connected to a vacuum pump 9. The fuel pump or compressor 7 and the vacuum pump 9 are driven from the shaft 4 through any suitable connections. The stationary member 5 is also rovided with ports 10, 11 and with oblique discharge assages 12 and 13 indicated in Fig. 4 and y dotted lines in Fig. 1.

A disk or throttle plate 14 bears against onesid'e'of the stationary member 5, and is providetl with openings that may be caused torcgjisterwithports 1 0, 11. This throttling late" is also provided with elongated openrugs-'15, I6, registeringwiththe passages 12 and 13" of the-member 5. The throttle plate cttnbe shifted circuinfe rent ial'l y by a worm andgear 221 A revolving member 17 is lieyed to theshaft 4 and bears upon the throttlin plate 14. This revol ving member is pmvid-d with a plurality of combustion chambers 18- and" spark plugs 19. Spark plugs 20- are positioned to ignite in the turbine such gases as were unburned when dis- I charged from the combustion chambers 18.

For cooling purposes the revolving member 17 may be provided with a plurality of fan' blades positioned at an angle to the direction of rotation, and vanes or shields 23 may be distributed over the surfaces of the stationary portions of the motor.

Suitable clamping means 24 are provided for holding the rotary member 17 in close contact with the throttle plate 14, and, as a further means of producing a gas-tight connection between 14 and 17, either may be provided with two annular tongues cooperating with annular grooves in the other as shown.

In the operation of my motor gas and air in proper mixture is forced into the reservoirs 6, and when the end of one of the combustion chambers 18 registers with the port 10 a charge of gas is supplied to the chamher, and further rotation of the revolving member brings it into a position in which the throttle plate seals the opening into the chamber, and the charge is then ignited, thus developing a high pressure in the chamber. Further motion of the revolving member, which is in a clockwise direction, brings the opening of the chamber opposite the slot 15 in the plate 1% and the passages 12 through the stationary member 5, and the gas is thus permitted to discharge against the vanes of the turbine. Further motion of the revolving member brings the combustion chamber into communication with the vacuum pump 8 through the ort 11, and the products of combustion stili contained in the chamber are thereby withdrawn. The combustion chamber next comes into connection with the second fuel compression chamber 10, which is preferably located 180 from the ulllcl fuel chamber, and a cycle, similar to that just described, is repeated, the fuel being received, exploded and the products of combustion discharged into the' turbine through openings 13 and undischarged products removed from the chamber through the second vacuum port 11. In the form shown six combustion chambers are provided in the revolving member 17, and each chamber discharges gas into the turbine twice in each revolution of the member 17.

It will be understood that modifications in the number of combustion chambers, fuel chambers, vacuum chambers, form of turbine vanes, and in other features of the particular form of device herein described may be made without departing from the spirit of my invention, and I, therefore, do not intend that the scope of the invention be limited otherwise than as required by the appended claims.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In apparatus of the class described, the combination of a turbine, a revolving member with combustion chambers, a stationary member between the turbine and revolving member and provided with passages for the admission of fuel to the revolving member and for the discharge of gases from the re volving member to the turbine.

2. In an apparatus of the class described, the combination of a turbine, a revolving clement carried on the turbine shaft and provided with con'ibustion chambers, fuel igniting means in said chaml'iers and revolving therewith, and a stationary member between the turbine and the revolving mem her, said stationar member bein adapted to form a closure or the combustion chambers and being rovided With spaced fuelsupply and gas-c ischarge ports.

3. In apparatus of the class described, the combination of a revolving element provided with combustion chambers, a turbine operated by gases discharged therefrom, and a plurality of fan blades spaced around the circumference of the revolving element.

4. In apparatus of the class described, the combination of a revolving element provided with combustion chambers, a turbine adjacent thereto and having its easing provided with spaced air controlling vanes, and fan blades on the revolving element for causing air to pass between the vanes on the turbine casing.

In testimony whereof, have hereunto set my hand and aflixed my seal.
